• Recyclinghaus

    The recyclinghouse is an experimental residential building in the Hanover district of Kronsberg. It is a prototype that tests the possibilities and potentials of various types of recycling in the real laboratory and shows a cycle-oriented and resource-saving planning approach.

    On the one hand, the recycling center relies on recyclable building products, such as the raw construction made of glue-free solid wood elements. On the other hand, recycled materials such as the foundation made of recycled concrete or wall insulations made from old jute bags are used. There are also large quantities of used components being used which, if possible, originate from the building stock of the client GUNDLACH or have been obtained locally. Particularly important is a recycling-fair design that allows the use and disassembly of the components without loss of quality or a sorted separation of the materials after the end of life.

    The construction industry is one of the largest waste producers and consumers of resources and a significant contributor to global CO2 emissions. When planning buildings, today it is mainly the energy consumption in the operation of a building that is considered. The considerable amounts of "gray energy" involved in the production of buildings remain largely unconsidered. Here, the existing building stock can also be understood as huge raw material storage. The recycling of building materials and materials as well as recycling-friendly construction methods will play an increasingly important role in the future.

  • New Istropolis

    CITYFÖRSTER and KCAP design a new cultural district for Bratislava, Slovakia. Trnavské mýto will house a state-of-the-art concert and congress venue and the area will be transformed into a modern open neighbourhood including a series of green and public areas.

    Immocap, the owner of Istropolis, has presented its vision of New Istropolis, developed in cooperation with the international architectural studios KCAP and CITYFÖRSTER. The project aims to bring Bratislava a world-class multifunctional cultural and social centre with top-level architecture, creating a long deserved cultural landmark for the Slovakian capital.

    The new multifunctional hall enables Istropolis to meet Bratislava's real needs and leverage the potential of Trnavské mýto, and will foster cultural and congress tourism. New Istropolis offers the capacity to host various events simultaneously, such as acoustic, rock, jazz, pop concerts, numerous events and cultural events, and conferences and congresses of all sizes. The hall will be able to hold three different events simultaneously and have a maximum capacity of 3000 seats and 5000 combined seats for sitting and standing. The unique in-the-round seating configuration brings the audience close to the stage, creating a sense of intimacy and connection with the performers.

    Trnavské mýto is a key location in Bratislava in terms of pedestrian movement, traffic, and potential contribution to urban development. The project aims to bring new life to this important part of the city that has been neglected too long. Besides the world-class cultural venue, there will be a park with promenade, fountains, and cycle paths. Public areas will be accessible to visitors throughout the day, while the square will support and develop community activities such as seasonal markets.

  • Buchholzer Green

    The development of Buchholzer Grün creates a residential area in an attractive location. The five-storey and the four-storey apartment buildings in combination with ten three-storey townhouses form the northern opening of the new quatier. The three new buildings develop a powerful, own identity, which incorporate the urban connection to the surrounding city districts and the neighbouring Podbielskistraße. The rhythmization in the height development as well as the verticality through the overlapping windows and balconies in the clinker facade are central design principles. The change of material makes the entrance areas clearly recognizable and at the same time they fit into the overall structure of the facades. The result is a robust, unpretentious and solid figure. The multi-storey housing units impress with an exciting mix of tenements and condominiums in different sizes, while the townhouses offer a small type of building as well as a large one and enable parking inside the house.

  • Residential Crown Carpark Windmühlenstraße

    The residential crown is a prototype of settlement 2.0. Rooftops of retail and office buildings, as well as parking garages, are activated, attractive locations are opened up, existing infrastructures are used more efficiently and the mixture of programs in the city centre is improved. The existing parking garage is complemented with penthouses as part of the renovation of the façade and entrance area. These residential units distinguish formally from the existing building structure and simultaneously give the building a harmonious completion.

    Entrances and circulation of the building have been reorganized so that independent addresses for the car park and the residential building are clearly recognizable. The residential building is accessed (barrier-free) via a representative lobby on the ground floor with exclusive elevators that lead directly to the central, landscaped residential courtyard. The residential units are accessible from this common space. Each apartment (50 to 120m²) has a spacious, private terrace overlooking the rooftops of the city.

  • Köstra Reuse

    The proposal for the revitalization of Königstrasse 1ab is based on the following 5 guiding design themes:

    Development of a building structure that completes the ensemble of the hotel and Königsstraße 1c, which incorporates heights and gradations, creates addresses and forms the prelude to Königstraße through its orientation towards the train station.

    Creation of lively, green passages with small-scale retail, gastronomy and areas for culture and events in the interior of the ensemble and a generous setback on Königstraße to provide more space for planting and passers-by.

    Enabling maximum exchange between inside and outside through diverse and generous entrances and transparent façades.

    Creating modern retail, office and restaurant layouts that can react flexibly to changing future requirements.

    Reuse of the existing load-bearing structure and individual components to minimize energy consumption and thus reduce CO2 emissions.

  • High Q

    Urban integration creates a neighborhood
    In its immediate surroundings, HIGH Q picks up on the typological and urban development characteristics of its neighborhood. The existing principles of block structures, incisions and polygonal high points are transferred to HIGH Q in order to create a harmonious overall urban image.
    On the west side of the construction site, a neighborhood square with outdoor gastronomy will be created at the interface between the office and the hotel, creating a lively meeting place for everyone. This square also serves as an entrance to the hotel lobby.

    Striking appearance creates identity
    Whether viewed from a passing train, as a pedestrian or from a bicycle, the HIGH Q always looks different and yet is unmistakable. The special façade design with 6 partial façades makes the high-rise appear slender and without a rear side, creating ever new impressions.

    Recognition value and an identity-creating design are an important requirement for this building in this exposed location. On the one hand, the façade and the striking shape create a variety of impressions depending on the viewing angle, while on the other hand the building also offers diverse and special situations in its immediate context. The undercut to Celler Strasse with its forecourt forms a clear address, the neighborhood square offers a common center for the neighborhood and the differently designed facades improve orientation and create different places.

  • Jugendherberge For Future

    As part of the CEWI-cooperation, Cityförster is developing an implementation concept that shows how the sustainable and careful renovation of real estate can be implemented in the DJH Landesverband Baden-Württemberg e.V.

    The mission for DJH Lochen is to be a flagship project for circularity, sustainability and sufficiency. This concept is translated to the offer of the youth hostel, and the architectural design and planning. Following the didactic focus of DJH Baden-Württemberg, the hostel should offer its guests an educational experience for sustainable awareness. This means programs with sustainability themes, active outdoor experiences, and workshops with local resources. These themes are also represented in the architectural concept. The main target groups are school groups, leisure (sports) groups, conference groups, and individual travelers like hikers, cyclists and retreat participants.

    The theme of sufficiency has guided the hostel to rethink its offer of rooms: smaller rooms to emphasize the outdoor experience, and the development of a summer house for the peak season. This summer house provides extra guest rooms in the warmer months, making a low-tech building without heating or cooling possible. The summer house transforms the old garage by extending it with a new floor on top. Upon arrival, the summer house is the eyecatcher of the circularity concept.

    The main goal of the renovation is to restructure the rooms and meet today's requirements. Because the exterior was renovated in 1982, the focus of the renovation is on the space plan and installations. This means a minimal renovation is sufficient. Where possible, building components are harvested on site or in the region, and repurposed in the summer house and the youth hostel. Where larger quantities of materials are needed, materials based on recycled resources and granulated raw materials are applied, for example recycled rubber, concrete and repurposed wood shingles.

    The beautiful location of DJH Lochen next tot the Lochenpass creates an inspiring natural environment in the forest on the hills. The existing outdoor facilities are upgraded, and new functionalities are added to extend the possibilities for outdoor activities. The new multifunctional outdoor spaces contribute to the sustainable outdoor experience of DJH Lochen.

  • Max and Moritz

    The primary focus of our project entails the resilient and environmentally conscious transformation of two Plattenbau buildings situated on the outskirts of Erfurt, with the objective of establishing a model that can be universally applied throughout the entire neighborhood. The volumes of the two buildings are enveloped by a prefabricated modular grid system, thereby creating an aesthetically refined and low-maintenance design. This approach facilitates not only the seamless integration of novel features, such as entrances on the north side and more expansive balconies on the south side, but also fosters the customization of living spaces and engenders a vibrant sense of community. Additionally, a continuous base serves to integrate the building into the surrounding street context, thereby reinstating a harmonious relationship with the adjacent neighborhood.

    Our material choices prioritize economic and sustainable utilization. Easily replaceable wood is employed for planter cladding and facade, complemented by natural fiber insulation and plant charcoal to offset the CO2 emissions associated with the concrete structure. Concurrently, the primary load-bearing structure is composed of concrete, ensuring both fire safety and minimal maintenance costs. A pivotal aspect of our climate-resilient transformation involves the incorporation of greenery on the facades to positively influence the microclimate in the vicinity of the building. This is coupled with a comprehensive rainwater management system, incorporating storage for utilization and retention during intense rainfall events. As a contribution to biodiversity, an assortment of plant species is judiciously combined to provide a year-round supply of flowers and sustenance for insects and birds.

  • Student City 2

    Our reconstruction concept of Tirana's "Student City 2" aims to show the great potential for particularly thermal energy savings in construction, modern student housing and is showcasing a well performing example how public and private sector can interact. As the buildings suffers from massive deterioration on the inside, main focus of the energy concept lays on a replacement of all basic infrastructure, including a adequate ventilation and heating systems as well as new windows as its centrepiece to remedy humidity. Different subdivisions of student rooms with joined shared bathrooms and modifications in use of common rooms allows spacious privacy and reacts on students needs. Applying a complementary colored orientation and material system for each dormitory allows visual indication of buildings, floors and rooms and provides "Student City 2" with a unique identity. As the roofs of the buildings offer common space, they can be used according to public or economic visions of its users and leverage "Student City 2" to be Albania's pilot energy efficiency project.

  • ecovillage - Tiny Living

    Sufficiency means shared luxury.

    The "Tiny Living" building is part of our project ecovillage in Hanover. It is located at the transition between the centre and the Green Ring and forms the interface between the intimate neighbourhood and communal space with a high degree of publicity.

    The L-shaped building consists of two stepped structures, which are accessed and connected via a generously usable arcade. On the one hand, the arcade enables a diverse exchange between the residents and, on the other hand, a very high degree of flexibility in the use of the building. Based on a grid, a wide variety of apartment sizes and forms of living can be offered and the living space can be adapted to future changing needs.

    The main focus in the development of "Tiny Living" is residential use. This is supplemented by a shared bicycle and storage room, two laundry rooms, a common room and an experiment room for water use and food cultivation operated by the entire ecovillage with access to the adjacent aquaponics greenhouse.

    Responsible use of building materials makes a significant contribution to the sustainability of the property. As early as the construction of the building, the conservation of natural resources is included through a design that is suitable for recycling. Through the targeted choice of materials and the possibility of a clean separation of the elements used, the amount of waste is reduced and the rate of reuse and recyclability increases. The greatest possible use of the renewable building material wood not only minimizes the CO2 emissions during the construction of the building but also serves as important CO2 storage.

    With the development of our ecovillage project in Hanover, there is a great opportunity to make an important contribution to future-oriented urban development with a balanced triad of social, ecological and economic sustainability. Find out more here.

  • Green, greener, Pelikan

    The design sets the urban development capstone for the Pelikanviertel. The original factory premises, the Neikes buildings, the FOUR and the "green, greener PELIKAN" - each stand alone and at the same time relate to each other. The self-similarity of the five buildings creates a strong, characterful unit that responds individually to its neighbourhood.

    Each of the five L-shaped buildings consists of a two-piece "bar" and a "head", which is formed by the accentuation of the high points by means of pyramid-like roofs and represents the prelude to the quarter. The roofs allow the maximum utilization of the plots and increase the recognition value. The range of uses offers variety - from green living, or mansard apartments with roof gardens, to hybrid studio apartments, to a variety of forms of use on the ground floor, which gives the street a unique character. The green oases in the courtyards provide a retreat and are the centrepiece of the design. Intensive greening of the balconies and facades form vertical gardens and, in addition to privacy, sun and noise protection, provide high-quality open space with privacy despite relatively dense development.

  • Urban Living. Vacant sites over the rooftops of the city

    In accordance with building regulations, one could build at least three more full floors on top of the existing multi-storey car park Briesestraße: There is a vacant lot on top of the car park. In static terms one or two additional stories are feasible. By converting the existing floors and adding floors on top a unique building is created with a special atmosphere and spatial quality for different user groups (live and work).

    The concrete areas between the ramps are removed, which allows daylight to reach below street level. The additional units of the 2 ½ storeys are built as a light wooden panel construction. The visibility of the past leads to special appreciation. Thus, the acceptance for a good remix in the neighbourhood is far higher than for demolition and a new beginning.

    The city block is structured by two cuts towards the public street. In this way, a community courtyard with neighboring pathways is created. The perimeter block development consists of six residential units and twelve townhouses on the east side. The street-facing brick facades are representative and respond to the importance of the entrance to the quarter. The spacious inner courtyard is zoned into a communal green center, surrounding paths and the private gardens lining the first floor apartments. All building entrances are barrier-free and all apartments are planned to be barrier-free. Each apartment has an outdoor sitting area and a small storage room. The underground parking garage is located in an L-shape under the northern block and is accessible from all staircases of the apartment buildings. There are also 145 bicycle parking spaces, some of which are equipped with charging stations.

  • Klimaquartier Würselen

    The Klimaquartier Würselen is characterized by strong open space references and clearly defined urban spaces. It mediates between the new and existing settlement bodies, the various neighborhoods and the open landscape in the east. In order to meet the current climatic changes and the scarcity of resources, the neighborhood will be developed in a space- and material-saving manner using timber construction; water and other resources will be used locally and treated on site.

    The new neighborhood landscape complements the existing open block perimeter while forming defined neighborhoods with intimate courtyards that combine village courtyard structures with play streets. The small-scale buildings surround the Green Center, which forms the heart of the neighborhood and functions as a meeting space for the surrounding neighborhoods.

    All buildings are based on the same construction grid, which corresponds to the deep garage grid of 5m. The bulkhead construction method, optimized for timber construction, forms the basis for the feasibility of the various building typologies. At the same time, repetitive building elements and construction principles ensure efficient planning and minimized construction times. The efficient basic structure allows for a variety of floor plan types - from one-room apartments to row houses to group apartments.
